Abstract (en)
[origin: EP0371250A1] A coordinated valve splitter assembly (30) includes a linear trim primary valve (32) in parallel with an equal-percentage-trim valve (38) to split fuel gas between primary nozzles (18) and a secondary nozzle (20) of a gas turbine combustor. In one embodiment, coordination of the actuation of the two valves is accomplished through rigid connection of the valve shafts. Shaped-cam and electronic actuation of the two valves is also disclosed.
